Default Starting HP

[joe2chillo]

I am creating a NPC Race for 5e. For hit dice I put in:
Hit dice: 9
Override Hit Dice Type: 6 (its a medium creature using d6 instead of d8)
Default Starting HP: 49

When I save this and try to use the Race in HL, it shows the HP as 58 instead of 49. Why is this? No mater what I change the Default Starting HP to it does not reflect this in HL. Why is this? How do I fix it? Thanks.
